GB/T 30839.34-2015Energy consumption grading for industrial electroheat installations - Part 34: Mains frequency induction channel furnaces (English PDF)

3.1 Unit power consumption

A test charge from the starting temperature of the heating, melting, and (or) the furnace temperature was raised to its rated main circuit supplied total power and Test

Charge weight ratio of units of kWh per ton (kW · h/t).

4.1

In accordance with the provisions of GB/T 30839.1-2014 8.1, the determined frequency induction furnace unit power consumption is divided into first, second and third class, up

Less than third-class indicators belong endures.

4.2

Different rated capacity GYT series determined frequency induction melting Tonglu, GYL series determined frequency induction melting furnace, GYX series frequency

Determined zinc melting furnace unit power consumption classification indicators are shown in Table 1, Table 2 and Table 3.
